Hi again.
I bought bundle. and I want to activate but It doesn't work.

whenever I click ' Validate License', there is an Error like below.

Error in the License Validation
Request to Sketchucation : ERROR_A04
Wrong Signature File - You nay have changed the computer name
It is advised to erase the signature file and revalidate
Do you want to open the folder containing the signature file?

I've tried deleting (SCFLicenseSignature - DO NOT MODIFY OR DELETE) file as I read in some posts, with no results.
and It makes 'B03' error......

Please help me how to solve it . Thanks.
